To all whom it may concern:

Be it known that I, GEORGE AUGUs'rUs Hnnnon, a subject of the Kingof-Great Britain, and atresident of the town of Pembroke, in theProvince of Ontario and the Dominion of Canada, have invented certainnew and useful Improvements in Car- I Stakes, of which the following isa full dei site stakes and engages with the top of the logs therebyholding the logs compactly together and preventing their rolling overeach other due to vibration when the car is running, to prevent thestake locking means from inadvertently loosening and generally tosimplify the several parts and adapt the same to better perform thefunctions required of them. r V

For a complete understanding of my invention reference is made'to thefollowing L of the tubular rod specification and accompanying drawingsill which,

' Figure 1 is a side elevation bodying the present invention. Fig. 2 isa fragmentary plan view of the sam I Fig. 3 is an end view of the carillustrate in Fig. 1. g I Fig. 4 is a fragmentary perspective viewcarrying the stake looking means. v Y

Figis a rspe'ctive tive form of stake.

V Fig. 6 is a fragmentary side elevation, partly sectional, of-thetubular member carrying the stake locking means andshowing analternative method of actuating the same.

of a car emview of an alterna Like ch'aractersof reference refer to llkeparts in the several figures.

Referring to the drawings, A represents.

7 a railway lumber car of the usual type equipped with the usual stakesB. The sides of the car'A are-provided with a plurality of equidistantlyspaced brackets 10 which consists of a back wall 11' having a pluralityof orifices therethrough whereby the brackets may be secured in positionby bolts or the like.

The side walls 13 of the brackets are formed integral with the backwalls 11 and i the; inner face of thesaid'side walls taper toward thebottom, thefr'ont of the brackets being opened and designed to beclosed'by a tapered locking member l l 'provided with an offset end 15which is the tubular spindle 16. This tubular spindleis slidably mountedin the brackets 17 located intermediate of the brackets 10 and the endof the spindle is formed with a threaded portion with which the screw 18makes threaded engagement."

This screw is rotatably mounted in'the bracket 19 and 't'o preventlongitudinal movement of'the screw a pair of collars 2O rigidly securedto are mounted thereon and designed to engage T with the. opposite facesof the said bracket.

Rotary motion is transmitted to the screw 18 byth-e hand lever 21 andwhen the spindle 16 has been moved to the-desiredposition'inwhichthelocking members 14 engage withthe'brackets '10, thehand lever 21 is engaged by a locking member 22, o thatalthough the carmay be subjected to undue vibration, there 'is no liability of the 4 ascrew 18 working loose. 7

1 The car stakes B' 'consist of a'plurality of tubular members 23having-their outer wall corrugated or serrated as shown at 24,thelowerends'of the tubular 'members,

being provided with a tapered portion 25 designed; to engage withthe'bra'ck'ets 10.

The upper end of the stakes'are provided with enlarged heads '26 'whichmay consist of flanges threaded or otherwise fastened said stake.

thereon or may be formed integr l' ithn the These car'stakes are locatedalong both lateral faces'of the car A,' being' arranged in pairsdirectlyfopposite eachother and when the caris loaded with logs in themanner shown in Figi3, the chain 27 or other flexi ble member extendsacross the top of the load to preve'nt displacement and rolling ofthe-logs w This chain is formed of two portions with the-outer ends ofeach provided with" elliptical links 28 adapted to T engage with thestakes B and when the chain is being tight ened these links will engagewith the corrugations 24. 7 g

' In tighteningthe chain it is only necessaryto adjust the length of thesame on the lever downwardly, and the chain will be tightened.

Referring now to Fig. '5,- an alternative I to those alreadydescribechbeing providedwith tapered ends 25 to engage with the-brackets 10.

In Fig. 6 an alternative means for actuating the locking members isillustrated in which the spindle 17 is provided with an nular flanges 32adapted toembracethe enlarged end 33 ofthe screw 34 making threadedengagement with the brackets 35 mounted on the car, which screwisprovided with a hand lever 36 wherebyit is manually actuatedi WV hen acar equipped in this nature is in use,-the stakes B-arepositionedand-the car loaded with logs-or lumber whereupori the chain 27 ispositioned witli the links =28-engaging the corrugations orserrations-2a of the stakes andthe lever- 29' is then adjusted and ondepression of the lever the chain 27 is tightened on the'load.

lVhen unloading. this car the operator r0- tates the hand lever 21so-movingthe tubular spindle 16 in a longitudinal direction therebywithdrawing the locking members 14 from engagement with-the brackets 10and permitting the stakes under the pressure of the load to' be movedlatera-llya and thus simultaneously released.

lVhen the' stakes'warefreleased, the chains 27 prevent the stakesfromfouling withthe logs and it will be readily seen that by providingthe serratio'nsor corrugations, the chain cannot slip.

Itwill be understood that-the tubular spindle16 does not rotate, butonly moves in a longitudinal direction and it will also be seen byreferenceto- Fig' 1, that the screw18 is only capable of rotation anddoes not move in a longitudinal direction; the necessary force toactuate thespindle 16 beingderived. from the rotation: ot-thie screwllVhen the locking members it are actuated by that typeof theinventionillustrated in Fig. 6, the lever 36 is manually rotated and the screw34- moves in a longitudinal direction drawing the spindle-17 withit to'disconnect the members l lrfrom the 'braelr -jets-10.- V

One of: the chief differences between this type'ofmechanism and thatillustrated in Figsi 1 andQ, istthat thescrewsfiltinmoving.:longituc'linally restricts the passage'be tweenadjacent cars, so that the operator has to stand well between the carswhen actuating-the'lever ti, whereasinthat form 1llustrated in Figs. 1and 2, the screw 18 does not move longitudinally and there is alwayssufficient clearance between the cars to permit of th e" operator of thelever '21 standing without 1 discomfort.

From this description it will be seen that I have invented a car" stakeF which can. be advantageously employed on lumber cars and wherein, theseveral stakes on one side of' the car can be simultaneously releasedtoliberate the lumber, the several parts being ,otan extremelysimplenature and not liable to get out of repair:

As many changes could bemade in the above description and manyapparently widely dilferent embodiments of my invention within thescopeot the claims constructed without departingzfrom the spirit orscope thereof; it'is intended that all matter; contained intheaccompanying specification and drawings sha'll beinterpreted asillustrative and not in a limited sense:-

lVhatI claim as my, invention is laTh e combinationwith a car of aplurality of stakes operatively mounted -there on-andmeansfor'simultaneo-usly releasing i said stakes: consisting of lockingmembers; a non-rotatable and longitudinal movable spindle carryingsaidmembers, and a screw coacting with the: said spindle.

2. In combination with a car ot a plurality of car stakes: operativelymounted thereon having. corrugations or serrations in the outer. walla'chain extending between the said stakes having links engagingiwiththe; coinrugations a tubular non-rotatable spindle mounted on-thei can;lockingmem= bers' carr-i'ed by thespindle designed to lock the stakes inposition, and a screw designed to; move "the spindle in -a longitudinaldirection. i r w 3. Incombination witha: car of pluralit'y of, stakesoperativelymounted thereon and arranged in pairs having theirouterwall-corrugated or serrated, means forlooking the stakes in positiomchains engaging with-the stakes-lever means for tightening the chains; alongitudinal extending non rotatable spindle slidably mounted on thecan, lockingmeans coacting-with the stakes carried by the; spindle andscrew means for actuating the spindle;-

In witness whereoffI have hereuntoset my -hand.
